You find the area of a circle by finding the radius and multiplying. The radius is a half of the diameter, so the radius of your circle is 10. The area of the circle is 100pi because the diameter is 10, and to find the area you multiply the radius by itself. 10×10=100

The area of a circle with a diameter of 20 inches is 314 square inches.

Given,

Diameter of a circle = 20 inches.

Pi = 3.14.

We are to find the area of the circle.

What is the area of a circle?

The area of a circle is given by : [tex]\pi[/tex][tex]r^{2}[/tex]

Where r is the radius.

And the diameter of a circle = 2r.

Diameter = 20 inches.

We can find the radius.

2r = 20 inches.

r = 10 inches

The radius of the circle = 10 inches.

Now,

We find the area of the circle.

Area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]

                          = 3.14 x [tex]10^{2}[/tex]

                          = 3.14 x 100

                          = 314 square inches.

Thus the area of a circle with a diameter of 20 inches is 314 square inches.
